## Labeling Configuration

```html
<View>
    <Header value="Rate this article"/>
    <Rating name="rating" toName="pdf" maxRating="10" icon="star" size="medium" />
     <Choices name="choices" choice="single-radio" toName="pdf" showInline="true">
        <Choice value="Important article"/>
        <Choice value="Yellow press"/>
    </Choices>
    <Pdf name="pdf" value="$pdf"/>
</View>

<!-- {
    "pdf": "/static/samples/sample.pdf"
} -->
```

## About the labeling configuration

All labeling configurations must be wrapped in [View](/tags/view.html) tags.

You can add a [header](/tags/header.html) to provide instructions to the annotator:
```xml
<Header value="Rate this article"/>
```

Use the [Rating](/tags/rating.html) control tag to apply a star rating with a scale of 10 to the pdf:
```xml
<Rating name="rating" toName="pdf" maxRating="10" icon="star" size="medium" />
```
  
Use the [Choices](/tags/choices.html) control tag to present classification options to the annotator:
```xml
<Choices name="choices" choice="single-radio" toName="pdf" showInline="true">
    <Choice value="Important article"/>
    <Choice value="Yellow press"/>
  </Choices>
```

Use the [Pdf](/tags/pdf.html) tag to render an inline version of the PDF data:
```xml
<Pdf name="pdf" value="$pdf"/>
```

### Input data

Label Studio does not support labeling PDF-formatted files directly. You should use the `embed` tag inside of your data for pdf loading:

```
{
    "pdf": "<embed src='https://app.heartex.ai/static/samples/sample.pdf' width='100%' height='600px'/>"
}
```
